Both of those two independent methods of investigation resulted in the same pattern which means it is significant.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc.
It is used to organize living organisms into specific categories.
Answer:
The net annual primary productivity of a particular wetland ecosystem is found to be 8,000 kcal/m2. If respiration by the aquatic producers is 12,000 kcal/m2/year
Gross primary productivity in a region of tropical forest is 1,200 kcal/m-Tyr. In this ecosystem, producers are. 25% efficient. 16,000 kcal/m²/yr
It would be B. Photosynthesis
Answer:
It varies due to their polarities.
Explanation:
Remember, a membrane is a semi-permeable membrane. There are some substances that can cross the membrane and others have to take different route. It all comes down to their polarity. If we were to examine a membrane made of phospholipid bilayers, one side of it has hydrophilic heads and the inside has hydrophobic tails. The membrane is therefore polar, allowing polar substances to enter in and out of the cell. Non polar substances, such as water have to take a different route, through special proteins called aquaporins.
